I can’t think of anything profound that I would do, read more, learn a language? I would probably do more of what I enjoy doing, walking along the beach and eating more food for half of the time and the other half I could be catching up on chores that I like to put off. I could even catch up with friends that I never seem to have time to see, get more uni work done and maybe even squeeze in an extra gym session. However, I’m not sure I could afford the lifestyle of never sleeping, at least when I’m sleeping I’m not spending any money!
